Aside from enjoying working with kids more, the payoff at the end is much bigger! As an English teacher, a foreign one at that, as the kids grow and their knowledge increases, I see them develop not only as students, but as people as well.
It's amazing to me seeing these little babies grow bigger and bigger and become little English speaking people who now from my standpoint not only learned a skill of speaking English, but developed a much larger understanding of different cultures and really the world as a whole. I know that the understanding they gain in my class will be huge parts of their lives going forward. I take a lot of pride in that.
